San Diego County coroner's investigators performed an autopsy Tuesday, but neither they nor police would say whether the shooting was self-inflicted or accidental.

Police Lt. Mike Hastings tells the Los Angeles Times the gun wasn't registered. Initial reports said he was shot in the head, but police now say it was the upper torso.

U-T San Diego reports that the group of 20 Scouts whose chaperones included the boy's father had arrived from Las Vegas on Sunday and had intended to stay until Saturday.

The program allows Scouts to camp, sail, kayak and do other activities at San Diego's Mission Bay.
